A person is able to take offense at all sorts of little things and his character, usually calm, becomes nervous, deteriorates. Falling in love is categorically not love in its essence. In love, people forgive each other, sacrifice something.
In the Bible, many words and teachings are aimed at creating love, and not at all about falling in love. Love in general does not concern specifically the relationship between a man and a woman. If a person works on himself, then he shows deeds of kindness to everyone who is near. Love is effective, falling in love is a purely inner passion. Poured out except through sexual intercourse, no more. Love is an act. Did you help grandma carry the bag? This is love. Many more examples can be cited, but I hope it is already clear. A person who cleans his heart from passions builds love for people and for God inside.
